The Alkngirrweltye Indigenous Land Use Agreement (ILUA) allows a section of land to be purchased by the Northern Territory Government for the purpose of creating an Aboriginal community living area. Without the ILUA, the transaction in the land may have been subject to the future act and right to negotiate provisions of the Native Title Act 1993 (Cth) (NTA). The parties also agree that any action taken under the agreement in order for the land transaction to occur, will not extinguish any native title rights and interests that may exist in the area - that is, the 'non-extinguishment principle' of the NTA applies.

This type of land transaction falls under Part 8 of the Pastoral Land Act 1992 (NT) and section 46(1A) of the Lands Acquisition Act 1978 (NT). Several other ILUAs have been made to create Aboriginal community living areas in the Northern Territory.
